Corrosion Control Design of Subsea Production System

Subsea production systems can save much construction investment, and are not affected by bad weather and have good reliablity, so thut the system is the key equipment for the deep water oil and gas field development and widely used around the world. Because steels may be corroded severely in sea and subsea production systems and can not be repaired after installation, it is very important to control the corrosion of subsea production systems. The corrosion control specifications of a common offshore project and three typical subsea production systems are analyzed and compared in this paper.
